The Legend of Zelda: Ocarina of Time - Skull Kid

Skull Kids are a race of small, mischievious beings that are usually found in forests. In Ocarina of Time, they are only found in the Lost Woods. It is said that when adults get lost in the Lost Woods, they become Stalfos, but when kids get lost, they will become Skull Kids. They are friendly to children, but tend to attack adults because they fear them.
